Are they really learning?

Deep Learning and the great AI revolution has finally arrived. Deep Neural Networks keep making incredible leaps in their ability to surprise us and beat humans at tasks we thought machines could never do better than us, like image recognition and play "Go". Or, we would like to think so. Recent developments and progress in machine learning and in deep learning in particular have been hailed as a new dawn for real artificial intelligence. AlphaGo win over world champion Go player Lee Sedol surprised many, since Go is a game much more complex than chess.
